Front

This circuit has a 24 volt battery and the resistor is 8 ohms. How many amps are running through the circuit?

Back

3 Amps

Front

What is the formula for Ohm's Law?

Back

V = I × R (Voltage = Current × Resistance)

Front

What does the term 'Voltage' refer to in an electrical circuit?

Back

The potential difference that pushes electrons through a circuit.

Front

What does 'Resistance' measure in a circuit?

Back

The opposition to the flow of electric current.

Front

If a circuit has a current of 2 Amps and a resistance of 4 Ohms, what is the voltage?

Back

8 Volts (V = I × R = 2 A × 4 Ω)
